Abstract
A surround-sound system for use with conventional TV sets, using a wireless remote bipolar rear speaker (or two conventional speakers fed out of phase) for the surround (difference) channels. The use of the rear speaker(s) and the mono (left plus right) front speaker on the TV set creates 'phantom' left and right front speakers, and allows full surround sound without modification to the TV set or additional amplifiers or speakers.
